## What it is
Vue.js is a progressive, incrementally-adoptable JavaScript framework for building web user interfaces, written in TypeScript. It features a truly reactive, compiler-optimized rendering system and scales from a lightweight library to a full-featured framework with an ecosystem including Vue Router and Pinia.

## Use cases
- build a single-page application with reactive UI
- create a progressive web app with incrementally adoptable framework
- scaffold a Vue project with TypeScript and routing
- build interactive user interfaces on top of standard HTML, CSS, and JavaScript
- migrate an existing Vue 2 app to Vue 3
- add reactive components to an existing server-rendered website

## When to choose
- you want an approachable framework with world-class documentation built on standard web technologies
- you need performant, compiler-optimized rendering with minimal manual optimization
- you want to incrementally adopt a framework, scaling from a library to a full SPA
- you value strong TypeScript support and a rich ecosystem (Router, Pinia, Vite tooling)

## When to avoid
- you need to support IE11, which Vue 3 does not support
- your team is deeply invested in another ecosystem like React or Angular with no migration plans
- you need a full-stack batteries-included framework with opinionated conventions like server-side routing out of the box
